This is great man. Try not to tense up your hands so much, and you should execute the exercise in a tempo where you will be able to play all the notes perfectly, cause that is always more important than go fast and sloppy.

Well, there is one problem about that not sounding right...you started your playing half beat before the backing track So, it would be nice if you could record it WITH backing track so it goes together and also you could try playing it with distortion - it shows you a lot of stuff you don't notice while playing with clean sound.

Second thing - i see you are working on your fretting hand position so it's good job m8!

Keep rocking!
